Description

Technical Field

[0001] The invention relates to the field of construction engineering, in particular to a dust reduction device for a closed working space. Background Art

[0002] In a closed working space, a large amount of dust will be generated during the production process. The dust suppression device can effectively reduce the concentration of suspended dust in the air. The air quality in a closed space is crucial to the health of workers. High concentrations of dust will be inhaled by workers, causing pneumoconiosis and other respiratory diseases.

[0003] Existing devices use spray to reduce dust. When the dust-laden airflow approaches the mist droplets, the airflow will bypass the mist droplets. However, due to inertia, the larger dust particles will continue to maintain their original direction of movement, thereby colliding with and attaching to the mist droplets. For some dust particles with smaller particle sizes, when their movement trajectories come into contact with the surface of the mist droplets, they will be intercepted by the mist droplets.

[0004] When performing spray dust suppression, it is necessary to manually adjust the spraying position back and forth to suppress dust at different locations, which is rather cumbersome and inconvenient to use. Summary of the invention
